  • Unless you make several trips to and from your mailbox every day, or sit by the window watching for the delivery person to arrive, it is next to impossible to know when you have mail...until now! The Smarthome SELECT Wireless Mailbox Reminder and Mail Alert System is an easy to install sensor (transmitter) and receiver that lets you know the instant your mailbox has been opened. This simple alert system will free you up from wasted trips to the mailbox and time spent looking outside, and allows you to get on with your daily routine. It is also a great solution for those with health problems or physical limitations and as security notification device to avoid stolen mail and possible identity theft if the mailbox is accessed during non-delivery hours.

    No Tools Required - Double-sided high temperature 3M adhesive strips with Velcro are pre-installed on the sensor. Simply install two AAA batteries (sold separately) into the sensor and stick it to the inside of your mailbox according to the directions and turn the sensor on. Then connect the power adapter to the receiver, plug it in, and you're ready. A screw and nut is provided if you wish to attach the sensor to your mailbox with hardware.

    Wireless Communication - The sensor and the receiver communicate wirelessly via radio frequency. The sensor identifies when the door has opened from its normal position and sends a wireless signal to the receiver, which then emits and audible and visual alert. Under typical conditions this communication will reliably work on distances up to 300 feet. Please keep in mind that several factors can bring this distance down including a high number of walls, outside radio interference, trees, thickness of metal used on mailbox, etc.

    Audible Indicator - When the sensor transmits a signal to the receiver that the mailbox door has been opened, a distinct audible beep will go off a few times letting you know that the mail has arrived. This can also be a great security tool if you are having problems with people tampering with your mailbox, as you will know the instant it is opened.

    Visual Indicator - Along with an audible indicator, the receiver will also display a flashing blue LED light when the mailbox is opened. If you happen to be outside or miss the audible Indicator or if you are hearing impaired, this light is an easy way to see that you have mail or that your mailbox has been accessed. A convenient reset button is located on the receiver to turn the LED light off.

    * Important Note: This product works on almost all curbside, wall mounted, and slot type standard mailboxes with horizontal hinges that allow the mailbox to open up or open down. It WILL NOT work on mailboxes with vertical hinges that allow a mailbox to open from side to side like a door on your home. Heavy metal mailboxes will also affect performance of this product (as it would most any wireless device) and it is not recommended for use in this instance.

    Frequently Asked Questions (FAQ)

    • Question: Is the Mailbox Reminder compatible with any home automation system such as INSTEON or Z-Wave?
    • Answer: No. The Mailbox Reminder is not intended to be a home automation device, rather it is a convenient, simple, reliable solution for letting you know when your mailbox has been opened.

    • Question: Does each Mailbox Reminder have a unique ID so that I don't get my signals crossed with my neighbor's?
    • Answer: Yes. Each Mailbox Reminder has been pre-programmed with different codes to prevent this issue.

    • Question: Will the antenna on the sensor stick out of my mailbox?
    • Answer: No. The antenna is only 3 inches in length so you can position your sensor accordingly and/or the antenna can be bent very easily to fit inside the mailbox.

    • Question: How does the sensor mount in the mailbox?
    • Answer: The sensor comes with a pre-installed Velcro strip. Simply clean the door of the mailbox well, dry it thoroughly, peel back the protective strip on the adhesive and securely fasten it to the mailbox door according to the instructions. The Velcro Strip now attaches with double-sided high temperature 3M adhesive strips to withstand extended exposure to heat.

    Still working Review by Faron
    Still working

    Its been near 4 years since I purchased this. I had to tape the antenna to the lid at first. It's been working great ever since. To bad they were made so cheaply that they're no longer carrying them.

    Great Unit. Review by Healer
    Great Unit.

    We have had this unit for a number of years. The first one finally failed after about 3 years when the battery contacts rusted over. We immediately got a 2nd one and it is functioning as designed.
    I think, however, that the cover of the battery could be better designed. Very useful item.

    Waste of time and money Review by Mickey
    Waste of time and money

    Have only had the unit for 6 months and it now will not work. I put in new batteries and no luck. The batteries fit in it very funky like due to one of the battery bays has the laoded spring on the POSITIVE terminal of the battery and pushes to the side for a poor connection. The battery cover does not fit tightly closed as it should. Total waste of my money and time it took to install!

    Update-Working Better Review by Richard
    Update-Working Better

    I cannot update my previous review so I'm adding a new one.
    I increased my review to 4 stars from 2.

    I've had this device since mid-August and it seems to be working a little better now. It trips about 80% of the time. It's loud so I have the alarm in the front window of the house where we usually aren't around.

    I used Velcro to fasten it to the mailbox door and moved it down to the middle of the door where it trips more often. Somehow the mailman still manages to get the mail in the box without tripping the alarm. Even I have been able to fully open the door and the alarm doesn't trip.

    The alarm can trip multiple times, so even if it's tripped and the blue light is blinking, if the door is opened again it will still beep in the house.

    The battery door isn't very secure and has partially opened. I added a small zip tie to the device to keep it closed and the battery in position. I can slide the zip tie off if I need to change the battery but it's been 3 months on the first one and even in below freezing weather it still trips the alarm.

    Suggestions for a better product Review by Michael
    Suggestions for a better product

    (1) Our mailbox is 260' from the house. I had to extend the antenna by 2' to get a reliable signal.
    (2) We have a metal mailbox so I had to drill a small hole in the side and feed my extended antenna to the outside of the mailbox.
    (3) The blue light had too focused a beam. I fixed this by sticking a very small piece of packing tape on the front of the lens.
    (4) It would be nice if the blue light switched off automatically after 12 hours.

    That said, it not a bad product.

    The alarm is triggered even if the mailman doesn't deliver any mail (because he has a package he brings to the house). Good, because we are alerted that he is coming.

    Smarthome Mailbox Alert Review by Grace D.
    Smarthome Mailbox Alert

    This product works great! Have used it now for three weeks and no problems. Took two minutes to setup. What I did to avoid the item from getting wet from rain, was to cut out the package cover and taped it over the mailbox alert. I would recommend this product.

    Worked Well for About a Year Review by DavidK
    Worked Well for About a Year

    The mailbox alert broadcaster stopped functioning reliably after about a year. If you shake it hard, it works, but that's not adequate to get the alarm working when the box is opened.

    Garbage Review by Dave

    I gave this a single star only because there is no zero star rating. Yes, 50-75 feet falls in the range "up to 300 feet", but I needed 200 feet (with perfect line of sight). Two days after it arrived, it was resting peacefully in the local landfill. Lesson learned. I ended up making my own with a Raspberry Pi Zero W ($10) , a case ($5), a switch ($2) and about 50 lines of Python code. Works perfectly and sends me an email when the mailbox door is opened.

    Waste of money Review by keith
    Waste of money

    Totally useless. The range is only about 50 feet and the quality was very poor. The on-off switch on the sensor was ready to break as soon as I took it out of the box. The receiver was far too loud and annoying and has no volume control. It's in a drawer now probably to never be seen again.

    It works as advertised, but we need a deluxe version Review by Floyd
    It works as advertised, but we need a deluxe version

    It worked. The mailbox unit had to be kept closed with tape because the case is so flimsy. The inside unit emits a grossly offensive sound that is far too loud if it is close by. A more tasteful sound and a volume control would be nice.

    So, make us an upgraded version - I will willingly pay more.
